Executive summary:

The melting point of the test substance was determined according to EU Method A.1 using capillary method. Five main runs were performed, and the mean final temperature was retained.

The melting temperature of test substance has been determined to be 81 °C.

Description of key information

Melting (i.e. solid-liquid transition) occurs at the temperature of 81°C. 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
81 °C

Additional information

A reliable experimental study, conducted according to EU method is available. Despite restrictions due to lack of experimental details, it is considered as a key study. The result is retained as key data.
